Answer:
a. $196
b. $88
c. $88
d. $88(x)
e. $20
f. $88
Explanation:
Given:
Rent = $20
Cost per Tux = $88
x = Number of tux
- Since $20 is rent regardless , how many tuxes we rent
Cost function C(x) = 88(x) + 20
A. Cost of renting two tuxes
C(2) = $88(2) + $20
= $176 + $20
= $196
B. All tuxes has same cost, so cost of second tux = $88
C. All tuxes has same cost, so cost of tenth tux = $88
D. Here variable cost means value of tuxes , so variable cost = $88(x)
E. Here rent is described as fixed cost = $20
F. Marginal cost = change in cost / change in quantity
= ${(2*88) -(1*88)} / 2-1
= $88
